Superb collection you have there. Indeed tough to tell the reps from the gens from the front, especially when they are mixed together and thrown on aftermarket straps such as yours. I was going to say that the 372 and 605 look gen but you beat me to it with your answers, as i am just seeing this thread now for the first time.
In any case - fantastic collection. Enjoy them all!
thank you , the 605 is indeeed the most precious to me, and the 029 t dial.
